There is no special requirement for women to eat normally during the physiological period, but some women will have particularly heavy bleeding (women with heavy menstrual flow) and excessive blood loss may result in dizziness and weakness. You can appropriately eat iron and blood-supplementing foods, such as animal liver, dates, eggs, etc., to correct the symptoms of dizziness and weakness caused by blood loss when menstruation is approaching. Patients who are afraid of cold and often have dysmenorrhea can take brown sugar and ginger water right before menstruation to expel the cold from the body and alleviate the symptoms of dysmenorrhea. Other substances that are easily digestible, easily absorbed and rich in vitamins and carbohydrates can be eaten to alleviate the low immunity caused by blood loss during menstruation.
